全自動(dòng)攪拌車在高溫下的兩點(diǎn)異常
在炎炎夏日，因?yàn)橥獠科骄鶜鉁馗撸詣?dòng)攪拌車發(fā)動(dòng)機(jī)冷凍液與空氣溫度差縮小，造成制冷系統(tǒng)制熱量縮小，使發(fā)動(dòng)機(jī)過(guò)熱，進(jìn)而會(huì)出現(xiàn)一系列的難題。下面全自動(dòng)攪拌車廠家給您講解一番。
In the hot summer, due to the high average external temperature, the temperature difference between the engine coolant and the air of the fully automatic mixer truck shrinks, resulting in the reduction of the heating capacity of the refrigeration system and the overheating of the engine, which will lead to a series of problems. Next, the manufacturer of the automatic mixer will explain it to you.
全自動(dòng)攪拌車發(fā)動(dòng)機(jī)的打氣指數(shù)降低：
The pumping index of the engine of the fully automatic mixer decreases:
平均氣溫越高，空氣的密度越小，發(fā)動(dòng)機(jī)的具體進(jìn)氣口量少。因?yàn)榘l(fā)動(dòng)機(jī)過(guò)熱，發(fā)動(dòng)機(jī)罩內(nèi)溫度高些，發(fā)動(dòng)機(jī)打氣工作能力減少，均使打氣指數(shù)降低。進(jìn)而導(dǎo)致發(fā)動(dòng)機(jī)輸出功率降低，以轎車行車乏力。另外混合氣體相對(duì)性濃稠，尾氣排放廢氣排放中的有害物濃度值擴(kuò)大，加劇空氣污染。
The higher the average temperature is, the smaller the air density is, and the specific air intake of the engine is less. Because the engine is overheated, the temperature in the engine hood is higher, and the engine's pumping capacity is reduced, the pumping index is reduced. This in turn leads to a reduction in the engine output power, resulting in a lack of driving power for cars. In addition, the mixed gas is relatively thick, which increases the concentration of harmful substances in the exhaust gas emissions and aggravates air pollution.
全自動(dòng)攪拌車發(fā)動(dòng)機(jī)點(diǎn)燃異常：
Abnormal ignition of the engine of the automatic mixer:
空氣溫度高，進(jìn)到氣缸的混和溫度也高，造成發(fā)動(dòng)機(jī)的溫度提高，而熱管散熱器的排熱高且效率低，發(fā)動(dòng)機(jī)處在超溫情況，發(fā)動(dòng)機(jī)燃燒室內(nèi)未燃混合氣體接納發(fā)熱量多，加劇焰前反映，非常容易造成燃爆。另外積存于發(fā)動(dòng)機(jī)燃燒室內(nèi)各構(gòu)件上的積碳產(chǎn)生熾熱點(diǎn)，易造成異常的點(diǎn)燃，加劇了發(fā)動(dòng)機(jī)的超溫，產(chǎn)生的兩極化，使之相關(guān)部伯造成熱形變乃裂痕毀壞。
The high temperature of the air leads to the high mixing temperature of the air entering the cylinder, which increases the temperature of the engine. However, the heat pipe radiator has high heat removal efficiency and low efficiency. The engine is in the over temperature condition. The unburned mixed gas in the engine combustion chamber receives more heat, which aggravates the reaction before the flame, which is very easy to cause combustion and explosion. In addition, the carbon deposits accumulated on various components in the engine combustion chamber produce hot spots, which are easy to cause abnormal ignition, and aggravate the engine's overheating, resulting in polarization, causing thermal deformation and even crack damage to the relevant parts.
在高溫自然環(huán)境里，全自動(dòng)攪拌車發(fā)動(dòng)機(jī)制冷系統(tǒng)的排熱溫度差小，排熱能力較差，發(fā)動(dòng)機(jī)非常容易超溫。所以日常使用要及時(shí)檢查各種事項(xiàng)以及零部件的使用。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://www.zvmc.cn了解吧!
In the high temperature natural environment, the engine refrigeration system of the fully automatic mixer has a small heat removal temperature difference, poor heat removal capacity, and the engine is very easy to overheat. Therefore, in daily use, various items and the use of parts should be checked in time. More relevant content will come to our website http://www.zvmc.cn Understand!
